Made entirely out of construction grade lumber, this staircase climbs the space between "here, and up there". Douglas fir, which is strong and brittle, was a great choice for the project. Built for a residence in a town 3 hours away by car, I managed to fit the entire thing, and my tools into my '91 suburu, travel the distance, and begin assembling it. Starting with the centerpost, which is 16 angled staves glued up and hand planed round, treads followed, then the ballistrade, and finally the two part bent lamination hand rail that keeps the whole thing rigid. Six years later, it is still holding strong.
